The .htaccess file have a great deal of possibilities. Today, let’s observe how we could protect our WordPress blog from scripts injection, and unwanted modification of _REQUEST and/or GLOBALS.
1- Paste the next lines into your .htaccess file. This file is located at the root of your WordPress install.
2- Always create a backup of one’s .htaccess file before editing it so, you can restore it if something went wrong.
